Apple believes it’s the highest taxpayer in the U.S, but the company has still been subjected to intense scrutiny because the majority of its cash isn’t located stateside, but in offshore subsidiaries scattered around the globe.

In a U.S. Senate Permanent Subcommittee this summer, Apple was accused of using Irish tax loopholes to avoid paying on about $44 billion in foreign profits. By basing ghost subsidiaries in Ireland, Apple has been able to not pay a considerable amount of taxes to any country. Now the Irish government is considering changing its tax code to prevent such behavior from happening in the future.

In his interview today at the AllThingsD D11 conference, Apple CEO Tim Cook responded to questions from Kara Swisher and Walt Mossberg about Apple taxes. Relating his time with the congressional subcommittee this past week, Cook, said that he felt strongly about how the company was portrayed by lawmakers.

Cook said that he wanted to be a catalyst for a discussion, coming to the hearing with a proposal rather than a defense, one for a revenue-neutral and major overhaul of corporate taxes nationwide.

Cook said that he felt simplicity was good, and how Apple approaches everything. The current tax system, he said, results in a two foot high tax return every year. When asked what he would like to do with it, he replied, “I would suggest we gut it.”

As part of expert testimony at today’s Senate Sub-Committee Hearing to Examine Offshore Profit Shifting and Tax Avoidance by Apple Inc., Professor J. Richard Harvey has made a compelling case that the tax system Apple is taking advantage of needs to have its loopholes closed.

Harvey — a distinguished Professor of Practice at Villanova University’s School of Law — says that while what Apple has done is acceptable under current International tax law, it still widely uses tax tricks and gimmicks to avoid paying what it fully owes.

At the hearing, there are basically two camps: those attacking Apple for using “gimmicks” or loopholes that other multinational corporations take advantage of, and those defending Apple while pointing out the obvious need for reform in the corporate tax code.

While Michigan Senator Carl Levin and Arizona Senator John McCain fall in the first camp, Kentucky Senator Rand Paul is clearly in the second. He said that the Senate should be apologizing to Apple during the hearing today, noting that “the committee needs to look in the mirror and see who created this mess.”
